Yes, I picked SOTU because that's a general audience, unlike economic clubs.
And heading in the direction of Dick and Jane doesn't mean that we ever reached it; according to https://community.jmp.com/t5/image/serverpage/image-id/8926i... recent SOTUs should be comprehensible to high school freshmen.
(full discussion at https://community.jmp.com/t5/JMPer-Cable/Regression-to-model... ; through 2018 — anyone have 2022?)
EDIT: keep in mind that the expected "general" audience for the SOTU has also expanded dramatically due to technological change in between 1790 and 2018...
